As solved on 30/11/2014 i hope this will help you:
Hi,
you should drop the comment-marker at the start of the line like this:
# Languages (Make sure there's a language file in resources/web/i18n when adding another language)
lm.languages=en,de,fr,hu
By the way: Only 2-letter codes are allowed.
Also create a hu.json on resources/web/i18n when adding another language and when editing user preferences that will show the option to select hungarian language.
I also started working on the portuguese translate of limbomedia, still testing BTW but will send to admin so new versions can have lots of languages.
